Chelton Flight Systems’ air data and attitude heading reference system (ADAHRS) has been added as an approved sensor on the FlightLogic EFIS supplemental type certificate (STC) for the Bell 206 and 407. Chelton’s ADAHRS is designed for fixed- and rotary-wing aircraft. The system interprets information from the pitot-static system and an outside air temperature probe to generate altitude, vertical speed, airspeed and air temperature.

Greece and Turkey have concluded an agreement intended to improve the air traffic route network over the Aegean Sea, according to NBAA. The route package, developed to handle the anticipated increase in air traffic associated with the upcoming 2004 Olympics in Athens, is scheduled to be implemented on Christmas Day. The new plan is expected to increase airspace capacity and improve efficiency while maintaining a high level of safety.

General Electric’s research arm and the U.S. Defense Advanced Research Project Agency (Darpa) have joined forces to develop an entirely bio-based jet fuel to reduce U.S. dependence on foreign oil. The main challenge is to make the conversion process efficient. The project envisions a conversion efficiency, by energy content, of crop oil to JP-8 surrogate of between 60 and 85 percent.

Green Flight International last month conducted the first flight of a jet using 100-percent biodiesel fuel. The experimental test flight was flown by an L-29, a military aircraft that is rated to fly on a variety of fuels, including heating oil, making it a “preferred platform” for testing biodiesel in jet engines.

Virtually all cargo-dedicated airplanes will be required to have traffic alert and collision avoidance systems type II (TCAS II) installed by December 31 next year under rulemaking published last month. Under a previous rule, the TCAS requirement was based on passenger seating capacity and therefore excluded cargo-only airplanes.

After reading Bill Wagstaff’s article on heli-logging in AIN, I feel compelled to respond. I lived and worked on Vancouver Island for over 20 years. Thanks to that experience, I think I can inject another perspective to the issue of the environment and economic soundness of heli-logging.

While Bombardier’s Wichita Learjet facility remains idle until next month during a planned, but unprecedented, four-month plant shutdown, company managers and machinists union representatives are “talking” about how to reduce production costs. According to a Bombardier spokesman, the Wichita facility ranks dead last in cost efficiency out of the company’s six aerospace manufacturing plants.

• About 400 Jet Commanders, Westwinds, Astras and Astra SP/SPXs are the subject of a proposed AD aimed at preventing cockpit fires resulting from a possibly defective oxygen shutoff valve that can create overheating in the system. Aviation authorities in Israel say they have reports of two incidents of fire in the cockpit of an 1124 and 1124A when the copilot turned on the system while the aircraft was taxiing.
